Pressure vessel steels not included in ISO 2604, Parts 1 to 6 -- Derivation of long-time stress rupture properties
This standard was last reviewed and confirmed in 2013. Therefore this version remains current.
Defines a procedure for obtaining and for assessing the data necessary to establish long-time stress rupture values for steels for pressure purposes for steels where properties different from those internationally agreed are being claimed. The purpose of a standard procedure is to minimize any differences in long-time estimates obtained in different countries due to differences in the quantity and duration of the data used and differences in the method of analysing the data.
